Hornady LNL, the cost is just a shell plate, and changing the plate is pretty fast, but it's time consuming to get the powder measure & drop readjusted. So I just leave it set up for the last caliber I did a big run of, and I use one of my single stage presses for everything else until I need to load a bunch of another caliber.
